Filed: 1992-06-19
Abstract: The prodn. of stable aq. polyurethane (PY) dispersions (I) from oligourethane-bis-biurets (II) comprises (A) synthesis of hydrophilically (ionically) modified (II) from polyols, opt. low-mol. wt. diols, ionic chain extenders, isocyanate components (pref. contg. diisocyanates or mixts. thereof with poly- and/or mono-isocyanates) and urea, (B) dispersing the solid (II) in water and (C) chain extension and/or crosslinking to give (I). Stage (A) is carried out continuously in a screw extruder, by introducing all the above components except urea at a first inlet (1) and reacting them in the first section to form a NCO prepolymer, then adding urea via a second inlet (2). The distance L2 between inlets 1 and 2 is between L1/1.6 and L1/3.0, where L1 is the distance from inlet 1 to the discharge point, and the residence time in the extruder (w.r.t. screw length L1) is 2-5 mins.. Pref. the 2-5 mins. residence time is obtd. by varying the screw speed from 200 to 350 (pref. 270-310) r.p.m. or by varying the extruder geometry L/D from 30-50, pref. at least 35 (with L = screw length; D = screw dia.).
